Popis: We synthesized 2,3,6,7,10,11-hexahydroxytriphenylene (HHTP), characterized it by electrochemistry, spectroelectrochemistry, and electron paramagnetic resonance techniques, and evaluated its cytotoxicity to human cancer cell lines. The results revealed that HHTP has accessible higher-oxidation states, especially the tris-semiquinone monoradical. This species is stable and is formed after being stored for months. HHTP exhibited cytotoxic effects on 5 human cancer cell lines, including glioma and lung cancer cells. The cytotoxic effect was evaluated based on the decrease in cell viability, increases in the percentage of cells with fragmented DNA, and elevated numbers of annexin V–PI-positive cells after HHTP treatment.
